trial of laryngeal preservation comparing induced ct followed by rt vs ct concomitant to rt

Conditions: Head and Neck Squamous Cell Carcinoma

Summary: this study compare the survival without laryngeal dysfunction 2 years after the end of treatment, obtained by chemotherapy followed by radiotherapy or chemotherapy with cisplatin administrated during radiotherapy.

in patients with tumors classified as t3 or t4 larynx and hypopharynx, the usually recommended treatment was total laryngectomy.this intervention allows to obtain locoregional disease control in 75% of cases, without laryngectomy tpf arm followed by radiotherapy was validated in a phase iii (gortec 2000-01), it will be the standard treatment. the rtog study concluded that chemotherapy administrated during radiotherapy became a standard of laryngeal preservation. taking together all these considerations, it is necessary to perform a direct comparison in a randomized trial to further test this hypothesis. chemotherapy followed by radiotherapy will be the standard arm. it hopes to increase the survival rate from 52% to 65% in the experimental arm.
